SHlNGLE-EDGER.

SPECIFICATION forming part of Letters Patent No. 560,147, dated'h'iay12, 1896.

Application filed A ril 23, 1895. Serial No. 546,897. (No model.)

To all whom it Hwy concern.-

lle it kn own that l, Hanvn r G. RICHARDSON, of Tacoma, in the county ofPierce and State of Washington, have invented a new and ImprovedShingle-Edger, of which the following is a full, clear, and exactdescription.

The object of the invention is to provide a new and improvedshingle-edger which is comparatively simple and durable in constructionand arranged for cutting the shingles accurately to any desired widthand without danger of the operator being liable to be injured by thesaws.

The invention consists principally of a feedcarriage for feeding theshingles to the saws and rollers for drawing the shingles through thesaws after the feed-frame is at the end of its inward movement.

The invention also consists of certain parts and details andcombinations of the same, as will be fully described hereinafter, andthen pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a side elevation of the improvement with part broken out,and Fig. 2 is a plan view of the same.

The improved shingle-edger is provided with a suitably-constructed frameA, in which is journaled a transversely-extending arbor B, carrying thesaws O, separated one from the other by collars D, the several collarsbeing fastened in place by a nut E screwing on one end of the arbor B.The latter' is provided with the usual pulley B, connected by belt withsuitable machinery for imparting a rotary motion to the arbor and thesaws Oi the direction of the arrow a.

Directly in front of the saws G is arranged a shaft F, mounted to turnin suitable bearings in the sides of the frame A, the said shaft beingadapted to receive the thin end of the shingles, while the butt-endsthereof rest on a carriage G, fitted to slide longitudinally on suitableguideways G, attached to the frame A. The carriage G has a horizontalportion, on which the rear portion of the shingle may rest, and avertical portion to engage the butt-end of the shingle. It will be seenthat the shaft F and the carriage G form the sole support for a shingleforward of the saws. In the rear of the saws C are arranged two feed ordraw rollers H and H, located one above the other and both journaled insuitable bearings in the sides of the frame A. The shingles, after beingcut by the revolving saws 0, pass between the rollers H and H, so as todraw the out shingles rearward out of the saws and from the carriage G,the latter being at this time at or near the end of its inward movement.

The shaft F, as well as the draw-rollers H and II, are rotated by apulley B on the arbor B by means of a belt I, which passes under thesaid pulley B and over the pulleys F H secured on the shaft F and rollerH, respectively. The belt I also passes over a large pulley I, securedon a shaft 1 j ournaled in suitable bearings in the lower part of theframe A, and on this shaft 1 is secured a conepulley 1 connected by abelt I with a large cone-pulley J secured on a transversely-extendingshaft J, journaled in suitable bearings on the frame A.

011 the shaft J is secured a pinion J in mesh with a large gear-wheel K,attached to a shaft K, journaled on the frame A and carrying anoval-shaped cam L, adapted to engage a friction-roller N on a lever N,fulcrumed at its lower end at N on the frame A.

The upper end of the lever N is pivotally connected by a link N with thecarriage G, so that a swinging motion is given to the lever N by the camL and causes a forward movement of the carriage G to feed the shinglesover the shaft F to the saws C to edge the shingles. A stop 0 on theframeAsupports the lever N at its return stroke, it being understoodthat the frame G can be either moved back by hand or by a suitableweight or other means.

It is understood that when the arbor B is rotated, as previouslyexplained, the shafts 1 J and K are rotated to cause the cam L to imparta forward swinging motion to the lever N and push the carriage G forwardat a comparatively slow rate of feed, so as to properly feed theshingles to the saws. It is further understood that the butt-ends restsquarely on the vertical part of the carriage G, which serves as a gage,so that the saws C edge the shingles accuratelythat is, the

sides of the shingles stand at right angles to the butt-ends. It is alsounderstood that by the machine described dimension shingles are producedthat is, shingles of uniform Width in each bundle, incontradistinction to random shinglesthat is, shingles of various widthsin a bundle.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent In a shingle-edger, the combination with aframe and a gang of saws thereon, of a pair of feed-rollers rearward ofthe saws, a rotary shaft mounted on the frame forward of the saws, acarriage mounted to slide on the frame
